public static NanoTime fromBinary(Binary bytes) {
 Preconditions.checkArgument(bytes.length() == 12, "Must be 12 bytes");
 ByteBuffer buf = bytes.toByteBuffer();
 buf.order(ByteOrder.LITTLE_ENDIAN);
 long timeOfDayNanos = buf.getLong();
 int julianDay = buf.getInt();
 return new NanoTime(julianDay, timeOfDayNanos);
}
